Using 70 \upmu m observations taken with the PACS instrument of the Herschel space telescope , the dust content of the nearby and interacting spiral galaxy NGC 3077 has been compared with the dust content of the isolated galaxies such as NGC 2841 , NGC 3184 and NGC 3351 .
The dust content has allowed us to derive dust-to-gas ratios for the four spiral galaxies of our sample .
We find that NGC 2841 , NGC 3184 and NGC 3351 have dust masses of 6.5–9.1 \times 10 ^ { 7 } M _ { \odot } , which are a factor of \sim 10 higher than the value found for NGC 3077 .
This result shows that NGC 3077 is a dust deficient galaxy , as was expected , because this galaxy is affected by tidal interactions with its neighboring galaxies M81 and M82 .
NGC 3077 reveals a dust-to-gas ratio of 17.5 % , much higher than the average ratio of 1.8 % of the isolated galaxies , evidencing that NGC 3077 is also deficient in H _ { 2 } + HI gas .
Therefore , it seems that , in this galaxy , gas has been stripped more efficiently than dust .
